V.2.2 Playing Out Test Patterns
The
Ultra
automatically starts to decode and play each new test pattern once it has been created.
Subsequently, the
Ultra
can be set to play out any test pattern included in the Generator window
by just clicking on it.
In both the above cases, the test pattern is output on whichever port and in whatever Video
Standard is currently selected in the Connections window. Other settings such as the current
Genlock selection are also automatically applied.
Any or all of these settings may need to be adjusted in order to deliver the test signal you require.
The full formal procedure for playing out a test pattern is therefore as follows:
To play out a test pattern:
1.
Set up the
Ultra
to direct the Generator output to the required port (as described in
Section B.1).
2.
Select the required Output Video Standard on that port (as described in Section B.1.5).
3.
Select the required Genlock on that port (as described in Section B.1.6).
4.
Click on the thumbnail that represents the image you want to play-out.
The image is then output via whichever device is currently linked to the Generator in the
Connections window.
5.
Make any required modifications to the way in which the image is played out (as described
in Section X).
6.
If necessary, adjust the timing relative to the chosen Genlock (as described in Section B.1.6).
7.
Where SDI outputs are used, there are further adjustments that can be made: see Section G.
Selecting a different pattern for play-out automatically terminates the current pattern that is being
played out and switches the Generator to playing the new pattern.
Note:
If the selected output video standard differs from the video standard for which the selected
pattern was created, then to fit the image to the output video standard, the image may need to be
resized either horizontally or vertically or both. For details, see Section X.2.
V.2.3
Image Data
Information about the image that is being used as a test pattern is shown on the Patterns page of
the right-hand panel when the cursor is on its thumbnail.
For video stills, the information shown comprises
information about:
The filename under which the source image is
stored on disk.
The type of image (e.g. JPEG)
The horizontal and vertical dimensions of image
in pixels
The size of the image, typically in MiB.
(1 MiB = 2
20
bytes)
Some settings controlling how the image is
interpreted (Resize type, Source range, Gamma).
The filename, type, dimensions and size data are just shown for information and cannot be
changed. The way in which the selected image is interpreted, however, can be refined, for example
by adjusting the value of gamma that is applied. This is described in Section X.
